Abstract

Detecting loss of resistance (LOR) can either be taught with dedicated simulators, with a cost ranging from €1500 to 3000, or with the ‘Greengrocer's Model’, requiring simply a banana.

OBJECTIVES

The purpose of this study was to compare three dedicated epidural puncture training simulators and a banana in their ability to simulate LOR. Our hypothesis was that there was a difference between the four simulators when comparing the detection of LOR.

DESIGN

Single-blinded, randomised, controlled study.

SETTING

Department of Anaesthesiology and Pain Therapy, Bern University Hospital, Switzerland.

Two of the three dedicated epidural simulators were rated more realistic in detecting LOR than the banana, but some participants preferred the banana to the other three simulators. Given the relative cost of a banana compared with a dedicated simulator, we suggest that a banana be used to teach the technique of LOR for epidural puncture.
